This invention-relates to slug casting machines of the' general organization disclosed in U; S.

LettersPatent No. 1,980,1101'toA. J. Stouges,

whereinazline ofmatricessupported in a verti- 5" c-ally'm'ovable'line transporter. or first elevator. is

presented to amold, themold filled with molten direct the slug properly into the-chute leading tothe.galley.-. Whenslugs of large point sizes are cast, especially those having overhanging faces (T-shaped or L-shaped-incross section), the action of the ejector blade on the shanks=of such slugs as they are pushed between the guiding surfaces, may have atendencyto tilt orcant them because of the relatively thin character bearing portions of the slugs capable of-cooperating with the guiding surfaces, with the result that the slugs may drop into. the chute lea-ding to the galley inaccurately.

guiding surfaces are dispensed with and, in order to insure that the slug is properly located for delivery to thenchute, adevice in the form of a bufferplateis' presented in front of' the mold when the latter is in the slug ejecting position;

and, as the ejector-blade moves forwardly to eject the slug from the mold, the buffer plate engages the face of the slug andis 'held yieldingly thereagainst until the slug is fully ejected, whereupon 40 the buffer plate is locked in its retracted position.

When the ejector blade-recedesthe slug is released, allowing it'to drop into the chute for delivery to the galley. With an arrangement of this kind, it is apparentthat, regardlessof the kind of slug cast (the machine herebeing equipped to cast slugs with overhanging faces, T-shaped or L- shapedincross section, as well as those without overhanging faces, as for. instancerecessed :slugs formed with transverse ribs beneath the character bearingportionof the slug? which render: them self-supporting-and plainslugs'offtheusual kind) the buiierplate will cooperate'with the ejector blade to hold theslug firmlyuntil it registers with the upper end oiithe chute;

According to: the present improvements, the

Because of the dilferent kinds of'slugsadapted to be castin themachine, the-chute leading to the galley is equipped with-relatively movable side walls adjustable to accommodate the slugs of different kinds. The side walls are sufficiently lowso that, in the case of slugswith overhanging faces, they may extend beneath such facesand in close proximity-to the shanks thereof andthus act to guide the slugs to the galley. When plain or recessed slugs are cast, the spacing of the chute walls is suchasto accommodate the fullwi'dth of the slugs. i

The relative movementof' the side walls of the chute'is efl'ectedby an adjustment of the right hand wall, the wall at the left being fixed. Whenthe parts are in normal position, the buffer plate is held in a retracted position away from the mold and the movableg'uid'e wall in aposition spaced from the fixed guide walla distance-sufficient to accommodate overhanging slugs having shanks of normal size (usually about't'en points). As the first elevator orline transporter descends, the movable wall is moved away from the fixed'wall to a distance somewhat greaterthan that sufficient to accommodateslugs" of the largest body, sizes. At the same time, the buffer plate is tripped and allowed to move-inwardly toward the mold" into' a positionfor engagement with the face of the slug before the latter'is fully ejected from the mold. When theparts have assumed theseipositions, the movable wall of the-chute will be held inits outermost'position-by the buffer plate.

After the'slug has beencast and the mold moved to the slug; ejecting position, ejection of "the slug follows, this operation beingeffected by; the ejectorblade which-engages the shank of the slug at its bottom edge,- pushingit against the butler plate whichyield's against spring'action as the -slug'is ejected; the'flat faceof the'buffer plate and the pressure exerted thereby onthe slug-:being' sufficient to holdthe slug-against tilt ing. When the bufi'er plate. has -yielded through a short distance, it trips-theradjustable chut'e'wall,

Fig. 6 is a view similar to Fig. 5, with the parts in the positions they will assume just prior to the ejection of the slug, and with the buffer plate in its innermost position cooperating with the chute wall retaining plate to hold the latter in its position of maximum separation;

Fig. 7 is a view similar to Fig. 5, showing the parts in the positions theywill assume just after the ejection of the slug, the slug shown being one with transverse supporting ribs; I

Fig. 8 is a view similar to Fig. 7, some of the operating parts however being omitted, and showing the use of a smaller plate on the mold cap tothe chute walls and illustrating the spacing thereof for a slug of large body size and which is equipped with transverse supporting ribs; and Fig. 11 is a perspective sectional view through I the chute walls and illustrating the spacing thereof when a T-shaped, slug is cast.

In'the operation of the machine, the matrices are first composed in line and transferred to a line transporter or first elevator A which thereupon descends to present the composed line to the face of a mold B previously located in casting position by a one-quarter rotation of a mold disc C on which the mold is mounted Thereupon the mold, by a forward movement of the mold disc is brought into contact with the composed line,

the mold filled with 'moltenmetal to form a slug' or linotype against the matrices which produce thetype characters thereon, and the mold thereafter, by a three-quarter rotation of the mold disc,

permost or normal position.

Machines of this character are usually equipped to handle slugs of different kinds. Thus in Figs. '7 and 10, there is shown a so-called recessed slug X having its face or character bearing portion a: supported by transverse ribs x arranged beneath the face portion and adjacent the shank while in Figs. 9 and 11 there is shown a slug Y, T-shaped in cross section, with a large overhanging face 3 and a shank 11 Another kind of slug (not shown but well known) is like the] slug Y but of L-shape in cross section, and still another kind 1 is the familiar plain or solid slug.

In order that the chute E leading to the galley may accommodate the different kinds of slugs, and guide them properly to the galley, one of the side wallsof the chute is made movable and is adapted to be automatically adjusted according to the kind of slug being cast. As shown in the drawings (Figs. 10 and 11), the chute E includes in part a fixed base portion E extending downwardly from the lower end of the mold (when the latter is in slug ejecting position) and curving forwardly to the galley F, a left side wall E formed integral with the base portion and which is provided at its upper edge with a laterally extending flange E This fixed portion of the chute is held in place by a lug e projecting forwardly from the flange portion E near the upper end of the chute and screwed to the usual vise frame G of the machine (see Figs. 4 and 7) The chute also includes a movable right hand portion E having a vertical wall member E curved to fit the base portion E of the chute and adapted, together'with such base portion and the fixed side wall E to form a guideway through which the slugs pass as they travel to the. galley. The vertical wall member E is likewise formed at its upper edge with a flange E extending laterally from said wall member in a direction opposite to that of the flange E3 but at the same level as the latter. When a T-shaped slug (such as the slug Y in Fig. 11) is cast, the side wall members E and E of the chute are positioned in closely spaced relation to accommodate the thin shank portion y of the slug and the flanges E and E extend beneath the overhanging face portion y of the slug, whereby the slug will be supported in an upright position and guided accurately into the galley. An L-shaped slug is handled in the same way'except that in such case only one of the flanges E or E willextend beneath the overhangingface. of the slug. However, for a recessed slug (such as the slug X in. Fig. 10), due to the presence of the ribs :2 the side walls E and E are spaced apart a distance corresponding to the full width-of the slug face, and the slug is delivered to the galley solely under the guiding influence ofthese side wallsE and E (the flanges E and E not being required for that kind of slug). The. same holds true in the case of a plain or solid slug which presents no overhanging face. The spacing of the chute walls E? and E depends entirely upon the kind of slug cast and is controlled automatically in accordance with a pre-v determined setting, as will presentlybe described.

In order that the right hand wall member E may be located'in its different positions of adjustment, it is mounted on a slide H arranged for limited movement crosswise of the machine in a horizontal portion J of a bracket J screwed to the vise frame, and wherein the slide is held by a tongue and grooved connection H The means for securing the member E to the slide H includes a reinforcing piece comprising a laterally extending flange E formed at the outer edge of the moves-inwardly toward the mold under the action its opposite end to a pin-H extending transversely.

through thehorizontal portion J of the bracket J said horizontal portion beingiformed with a recess- Jfi-at: the top and nearits right end to provide clearance for the pin'H and spring H during the movement of theslide' (see Figs; 1, 3, Sand 7). However, nearthebeginningof a machine cycle ofoperation, the-slide His moved to its extreme rightmost position-where it'is' held pending the ejection of the 'slug', by abufferv plate K formed with aflange K which engages at the left of a vertical plate H secured tothe slide H (see Figs.

4" and 6) i The purpose of the buffer plate K just alluded.

to, is to. hold the slug against tilting or canting so that it maybe positioned-properly for entry into the chute. It is arranged opposite the mold in the'slug ejecting position thereof, is as long as the'molditself and wide enough to accommodate slugs .ofthe largest point sizes. This buffer plate has secured to it,.a fiat padding strip K so as not. to damage. the. faces of the slugs, and is carried. atthe inner end of. a slidable member K arrangedifor limited fore-and-aft movement in another horizontalportion J of the bracket J andwhich extends at right angles to the portion 'J that: supports the slide H. The slide K is tongued' and: grooved, as at K4, in the bracket J1 and is urged inwardly toward the. mold by a .compression spring K v housed in a longitudinal recess K formed in the right side wall of the slide K and which is confined at its ends between the buffer plate Kanda small plate K" fastened at the front end of the horizontalfore-and-aft portion J of the bracket member J and formed with atongue projecting into the longitudinal recess K that houses the springK (see Figs. 1 andv '7) In the normalposition of the parts, the buffer plate slide K is spaced somewhat away from the mold (see Fig. 5), in'which position it is held by an eccentric K fixed at the lower endof a vertical pin extending through a bearing lug. J formed on the bracket J, and which pin at its upper end, has fixed thereto an arm K urged in a direction to wedge the eccentric K against the slide K by aspring. K that presses against the front edge of the arm K and which seats in alug J formed on the bracket J Now, when the machine cycle of operations is inaugurated. the slide I-I carrying the movable chute wall is moved from itsleftmost. position,

(Fig; 5)' to its rightmost position. (Fig. 6), wherein the chutewallshav'e-their maximum: degree of separation which; as. previously stated, is slightly more. than that necessary. to 'accom modate the largest slug that the machine willcast. As the slide nears its rightmost position,

pin H fixed therein and which extends forwardly through a slotformed'in the horizontal portion J. of the:bracket J engages at its outer end against a cam surface K formed at the. end

ofthe arm K that operates the eccentric K5,. causing said armto pivot against. theaction of the spring K thereby, turning the eccentric and releasingthe buffer slideK, whereupon the latter;

ofits associated spring K until arrested by ablock K 'screwedat the front end of the slide and banking against the supporting bracket J at the front end of .its horizontal portion J (see Fig. 6). When the buffer: plate is-in its innermost positiomthe flange K thereon engages at the left of thevertical plate H carried by the slide H(see Figs. 2 and. 4) thus locking said slide in its rightmost position, all as-previously described.-

The means for effecting the movement of the slide H tothe right includes a lever L pivotally connected at its upper end to the vise cap-and which at-its lower end is bent inwardly (see Figs.

1 and-2) toengage at the left of the pin H understood that the cam A on the first elevator is sulficiently long to hold the slide H in its rightmost position until the buifer plate has-had an opportunity to reach its rearmost position.

Although the lever L and the arm L fastened thereto act as a unit, actually they are formed in two parts to permit of slight angular adjustment when required, the devices for this purpose including a set screw 1 threaded through a lug 1 formed on the lever and banking against the arm L at the end 1 thereof oppositethe cam follower L. It might also be statedhere that the pin H through which the slide H is actuated to. theright is provided at its outer end with a round-headed screwh that bears against the cam surface K of the arm K and which is threaded into the end of the pin likewise to permit slight adjustments when required.

After the'casting operation, the mold disc C is moved throughthree-quarters of a rotation to bringthe mold B into the slug ejecting position,-

the first elevator meanwhile ascendingto its uppermost position, but this latter movementof the elevator will have no eifect upon the slide H and consequently the movable side wall of the:

chute, since, as previously stated, the slide H is held in its rightmost position by the buffer plate K.

When the mold has reached the slug ejecting position, the mold disc comes forward as usual to a position where its front face is in line with or.

positioned slightly to the front of the chute leading.to the galley (see Figs. 2 and 7); andimmediately after the mold disc starts its forward movement, the ejector blade D likewise moves forwardthroughthe mold slot and engages the rear or bottom edge of the slug; The continued forward movement of the ejector-blade effects the ejection of the slug from the mold, but before the slug clears the mold, the front face thereof engages the buffer plate K and, as the latter is heldyieldingly against the slug, the slug is prevented from canting or' tilting as it leaves the mold. The buffer plate continues to yield against the action of the spring K 'until'it reaches its outermost or forward position (see Fig. '7), at which time the slug will be entirely clear of-the mold, the slide H in the meantime-having been released when thebufier plate K moves out of theway of the plate H carried by the slide. The slide H, immediately upon its release, moves to the left under the action of the tension spring H associated therewith and, in so doing, releases the arm K which thereupon is free to efifect the locking of the buffer plate slide K in its forward position.

As the chief function of the slide H is toposition the movable side wall of the chute leading to the galley to accommodate slugs of different kinds, the distance through which it moves to the left will vary in accordance with the slug .being cast. Accordingly, the slide H is arrested, in its movement to the left, in different positions, as determined. by the banking of a pin H associated with said slide against a plate b screwed to the mold cap or against the upper edge of the mold cap itself.

The pin H extends in a fore-and-aft direction and is mounted in a boss H formed in the slide H and yieldingly held in close spaced relation with the mold disc (when the latter is in its forward position during the ejection of the slug) by a spring H encircling an inner reduced end of the in and confined between the outer large portion of the pin and a shoulder presented by a Wall H in the hole drilled in the boss to receive the pin (see Fig. 5). The inner reduced end of the pin H extends through the wall just mentioned and is provided with a nut H threaded on the end of the pin and a washer H that banks against said wall at the face thereof opposite that against which the spring banks, thus limiting the movement of the pin toward the mold disc. The pin H is yieldingly mounted for safety and to prevent damage to the parts in the event the mold disc is pulled forward by hand for any reason.

The distance through which the slide H carrying the right hand wall of the chute is adjusted to the left is varied according to the kind of slug being cast, and such variations are effected by using plates b of different sizes on the mold cap. Thus, as shown in Fig. '7, where the slug is of the recessed variety, the plate I) is large, and accordingly the spacing between the side walls of the chute will be correspondingly large to accommodate slugs of this size. For slugs of the same kind but of a smaller point size, the plate is correspondingly smaller as shown in Fig. 8. For overhanging slugs, like the T-shaped slug shown in Fig. 9, no plate need be employed and in such instances, the pin H' may bank directly against the mold cap or the chute wall be allowed to return to its original position as determined by the engagement of the lever L with the stop pin 7. Under such conditions, the plate H passes behind the overhanging face of the slug and the right hand wall E of the chute will be located in its innermost position wherein the distance between the two walls E and E will be sufficient merely to accommodate the thin shank of the slug.

With the walls thus adjusted properly to receive the slug, the latter, as the ejector blade recedes, is released and thereupon drops into the chute for delivery to the galley. In this connection, it may be noted that the flanges E and E curve inwardly at their upper ends toward the base E of the chute (see Figs. 2 and 3) in order to insure that slugs with overhanging faces will pass properly into the chute when released by the ejector blade.

After ejection of the slug and delivery thereof to the galley, the mold disc recedes, withdrawing the plate b on the mold or the mold itself, as the case may be, out of the path of the pin H carried by the slide H, whereupon the latter,

under the influence of its associated spring H will be returned to its extreme leftmost position, which is determined by an adjustable banking screw 1, against which the slide actuating lever L at its lower end abuts. With the buffer plate K locked in its forward position and the right hand guide wall in its leftmost position, the parts are again normal and ready to be reset during the casting of the next slug.

As a precautionary measure, in the event the buffer plate is not actuated to its innermost position, wherein it holds the slide H against movement to the left during casting and prior to the ejection of the slug, which might result in damage to the parts, a safety device is provided in the form of a yieldable pin M horizontally arranged in a boss J carried by the supporting bracket J and in line with the cam A carried by the line transporter. The pin M (Fig. 5) is formed with a collar M spring-pressed against a pin M extending radially through the boss and which determines the outermost or normal position of the pin M. When the first elevator descends to position the parts, as previously described, it will engage the pin M, pushing it to the right and, if the parts have been properly set, said pin will enter a recess is formed in the bottom edge of the buffer carrying slide K and which will be brought into registry with the pin when the slide is in its rearward position. In such circumstances, the pin M will have no effect, since prior to the time that the slug is ejected from the mold, the first elevator will have ascended to its uppermost position, allowing the pin, under the influence of its spring, to be withdrawn from the recess is, thus freeing the slide K and allowing it to move forwardly, in the manner described, when the slug is ejected. However, in the event the buffer plate has not been properly located in its rearward position during the initial phases of the machine cycle, the recess is will not register with the pin M and the latter will bank against the slide K The pin M, therefore, will not yield as the first elevator A descends, but rather will act to arrest the elevator before it reaches its lowermost position, in which event the customary vise automatic will act to stop the machine,
